Time-Release Nutrients for Yeast Winemakers commonly make incremental additions of nutrients during the first half of the fermentation as a means to manage the fermentation rate through the quantity and composition of available nutrients. The nutrient demand is greatest during the exponential phase, when cells require more organic nitrogen rich compounds to reach the desired level of biomass. This leaves limited nutrients available for subsequent generations of yeast to maintain the biomass through to the end of fermentation. Incremental addition assures nutrient availability to these later generations of yeast. The Micro Essentials Complete-TR and Micro Essentials Boost-TR were developed as a solution to the logistical difficulties of incremental additions. Nutrients are compressed into tablets creating a distinct time-release profile, delivering the proper dose and composition of nutrients as needed throughout the fermentation with a single addition.
Micro Essentials Complete-TR • Combination of two tablets, each with a distinct time-release profile and nutrient composition • Both tablets are added together at onset of inoculation • One table contains a higher percentage of organic nitrogen, vitamins, minerals, and yeast survival factors, and has a faster dissolution rate to build biomass during the exponential phase of yeast growth • The other tablet has a higher percentage of inorganic nitrogen and a slower dissolution rate to provide nutrition through the fermentation Micro Essentials Boost-TR • Contains a higher percentage of inorganic nitrogen along with vitamins, minerals, and yeast survival factors • Slower dissolution rate to provide nutrition throughout the fermentation • Used to supplement Micro Essentials Complete-TR in musts that have lower YAN or that are known to be problematic
